When you hear a "pure tone" ... like the sound of a tuning fork
or an audio oscillator ... the pitch you perceive tracks directly
with the frequency.
The 128 Hz tuning fork will sound lower than the 512 Hz one.
In fact, it will sound exactly two octaves lower.
Answer : The time taken for the concentration will be, 7.98 seconds
Explanation :
First order reaction : A reaction is said to be of first order if the rate is depend on the concentration of the reactants, that means the rate depends linearly on one reactant concentration.
Expression for rate law for first order kinetics is given by :
![k=\frac{2.303}{t}\log\frac{[A]_o}{[A]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B%5BA%5D_o%7D%7B%5BA%5D%7D)
where,
k = rate constant = 
t = time taken for the process = ?
= initial concentration = 0.860 M
= concentration after time 't' = 0.260 M
Now put all the given values in above equation, we get:


Therefore, the time taken for the concentration will be, 7.98 seconds
Answer:
what is that supposed to even mean
Explanation:
Force your doing it purposely and acceleration it’s just happening
